The Phase I effort was successful in experimentally showing feasibility of a combined isotope transmitter that can be developed and demonstrated under the Phase II program. The initial experimental results give the window of gas mixtures for a stable discharge. Laser extraction tests were accomplished with C12/C13 mixtures to give guidance for further work to increase laser gain. For application to improving the effectiveness of detection algorithms, mode analysis was performed and showed that important improvements in shot-to-shot waveform and total energy stability can be achieved with novel resonator configurations. Initial analysis was performed to identify specific combined C12/C13 lines important for chemical vapor and aerosol detection and to guide further testing.
